Floating-Caliper Brake Lining Assembly for Rattle-Free Reset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing brake pad arrangements for sliding caliper disc brakes face challenges in optimizing the prestressing of brake pads to prevent rattling noises and residual grinding torques, while also ensuring sufficient guide length for the caliper to move without tilting, which is often hindered by limited space and the tensioning of the caliper mounting.
Innovation Solution
The solution involves a pad spring arrangement with individual pad springs that are designed to provide an active restoring force by being pressed against the pad carrier shaft, allowing for a longer guide length and relieving the inner saddle bearings, enabling a more efficient reset behavior of the brake caliper and securing the brake lining with cylindrical bolts and a special shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lining spring arrangements with one or more lining retaining springs are used to prestress the brake pad, then rattling noises are avoided, but the caliper bearing is tensed and residual grinding torques occur
Solution Approach 1:
The patent extracts the harmful function of the lining retaining spring from the system by removing it entirely. Instead of using a separate retaining spring that causes harmful tensioning, the brake lining is secured through its structural design with the brake pad and caliper bearing, eliminating the source of residual grinding torques while maintaining reliability through proper mechanical engagement.
2Stability of the object's composition
If the guide length of the caliper bearing is increased to enable the brake caliper to move without tilting, then sliding behavior is improved, but the space available in the vehicle is insufficient
Solution Approach 1:
The patent resolves the space constraint by changing the dimensional arrangement of the guide elements. Instead of extending the guide length in a linear fashion that consumes axial space, the design uses radial positioning of guide surfaces and optimized angular orientation of the caliper bearing, achieving stable sliding motion without tilting while maintaining compact installation dimensions.
3Ease of operation
If the brake lining is secured with connecting elements and special shape, then the caliper bearing is relieved and reset behavior is improved, but the structural complexity increases
Solution Approach 1:
The patent merges multiple functions into integrated components. The brake lining design combines the securing function, guide function, and structural support function into a unified structure that works in conjunction with the brake pad and caliper bearing. This integration eliminates the need for separate retaining springs and complex mounting mechanisms, achieving improved reset behavior without excessive structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the reset behavior of the brake caliper, reduces residual forces on the brake disc during non-actuation, and allows for a more compact installation by optimizing the guide length and structural design, thereby improving the sliding behavior and resilience of the brake caliper.
Implementation Method 1
When clamping, i.e. when moving the pad in the direction of the brake disc, this results in an elastic deformation of the spring legs and, as a result, in a spring force that counteracts the pad displacement.
Implementation Method 2
Since the spring legs are supported by friction, the spring can position itself in the brake pad carrier shaft according to the state of wear of the brake pad.

AI summary
The invention relates to a brake lining assembly for a floating-caliper disk brake, comprising a brake carrier and a brake caliper that can be moved relative to the brake carrier, wherein the brake carrier accommodates at least one brake-application-side brake lining and one reaction-side brake lining in respective brake lining channels, wherein the brake linings can be applied to a brake disk, and comprising at least one lining spring assembly (10, 11, 20), which causes bracing between the brake carrier and the reaction-side brake lining, and wherein at least the lining spring assembly (10, 11, 20) of the reaction-side brake lining is guided from a peripheral side of the brake lining, where the lining spring assembly is retained between the brake carrier and the brake lining, to the top side of the brake lining on the open side of the brake lining channel facing away from support surfaces (A) and is retained on said side on a securing element (8) fastened to or formed on the brake caliper.
